It is said the southern Rhoyne becomes so wide that someone in its center cannot see its shores.[2] The Volaena reaches the Rhoyne just north of Volantis. A giant delta forms at its mouth, upon which Volantis sits along the Summer Sea.[3][1] The Long Bridge crosses the Rhoyne in Volantis.

The Rhoyne is known for its river pirates, who hide on and around the many islands of Dagger Lake.[4] Timber from the Forest of Qohor is shipped downriver, since the cities and towns of the southern Rhoyne have depleted many of their forests.[5] Giant turtles known as the Old Men of the River live in the Rhoyne.[2]

History

During the Long Night, the Rhoyne may have frozen as far south as its confluence with the Selhoru.[6]

The watershed of the Rhoyne was the homeland of the Rhoynar, an iron-working people who founded several city-states along its banks.[7] The hills and forests contained savage peoples, but the powerful Rhoynar ensured peace along the river and its tributaries.[8]

After conquering the Old Empire of Ghis, the Valyrian Freehold began expanding west and founded their first colony, Volantis, at the mouth of the Rhoyne. The Rhoynar served as a buffer against Valyrian expansion to the northwest, however, so the Valyrians instead pressured the Andals to the west.[9]
